And me too :-(  4.1 is a bit ahead, so I may volunteer to do the actual
implementation if that happens during the summer :-)
I'll definitely help reviewing the codes if anyone undertakes the project.

It is almost OK: we don't need the #else-part, because the generic
version will be automatically selected if the ordinary overloads are
commented out by the #if part.
